Check this out, physical cryptocurrency in the form of polymer banknotes. I think this is a very cool idea that could help bridge the "fintech generation gap".

Pretty interesting, I wonder how they are preventing fraud.
My guess is they'll be keeping the private address to themselves, while displaying the public address on their bills so the balance can be verified. This would require trusting the company issuing the bills and anyone else with access to the private keys (staff, etc).
Yeah, like a closed system that uses digital currency, I just wonder if someone get's your ID number or whatever QR code represents if they can just print a copy of your bill. Sort of like how registers and atms need to ask for a pin, because the card number isn't very well protected.
That's a good point. It will be interesting to see what safeguards they can put in place to prevent QR forgery. I'd assume the forger would need sophisticated counterfeiting equipment in order to replicate the UV watermarks. This may not be economically viable for isolated thefts, however if they had means to obtain QR codes for numerous bills, it could be worthwhile.
To correct what I said earlier, here is how the public/private keys work:
"The private key can be used to take the balance from the banknote, Please note that the note becomes void if the key is exposed (you need to peel the public key off to see this key)."
